Ms Britney showed off her new chocolate tresses this week when she attended The Elton John AIDS Foundation Party in LA and we were very impressed with her subtly sexy attire! To go with her deliciously dark do she chose a backless Michael Cinco Couture dress that showed off her toned body to perfection, as well as accessorising with statement De Grisogono jewellery. While she could have dialled down the orange a tad we think our favourite pop-starlet looked sweet and sexy in the sparkling black dress. For Brit’s dramatic look we've chosen this embellished Elliot Claire evening dress that has the perfect amount of back-flash and sophisticated long length. To really make the most of this feature wear your hair up with a selection of glittering hair slides while adding height to your full length look with some extra-high heels in SS13-conscious metallic. Elliot Claire Black Beaded Embellishment Evening Dress, £180, Moda in Pelle Instinct Gold Snakeskin Peep Toe Court Shoe, £69.95, Johnny Loves Rosie Delicate Flower Hair Clip in Silver, £20, Johnny Loves Rosie Delicate Flower Hair Clip in Purple, £20.
